An Analysis Of Stakeholders Communication In Collaborative Software Development Projects, Wei Zhang

Dissertations, Master's Theses and Master's Reports

Software development is a multidisciplinary collaboration involving many stakeholders. However, existing software development processes exhibit many issues related to that collaboration. Because prior research on stakeholder analysis and teamwork revealed the importance of communication, this study analyzed stakeholder communication with reference to team activities as a social and cognitive process. The study’s goal was to understand the collaboration process during software development and to delineate factors that influence this process. We focused on communication between the software developers and their clients during the requirements gathering phase, the team process, and the inter-team and interdisciplinary collaboration, in particular between software engineers …

Getting Active With Passive Crossings: Investigating The Efficacy Of In-Vehicle Auditory Alerts For Rail Road Crossings, Steven Landry

Dissertations, Master's Theses and Master's Reports

Train-vehicle collisions at highway-rail grade crossings continue to be a major issue in the US and across the world. Installing additional hardware at individual crossings is expensive, time consuming, and potentially ineffective. To prevent recent trends in safety improvement from plateauing, experts are turning towards novel warning devices that can be applied to all crossings with minimal cost. In-vehicle auditory alerts (IVAAs) could potentially remedy many of the human factor issues related to crossing safety in a cost effective manner.

This thesis presents a series of experiments designing and testing an IVAA system for grade level railroad (RR) crossings. Study …

East-West Cultural Differences In Visual Attention Tasks: Identifying Multiple Mechanisms And Developing A Predictive Model, Yin Yin Tan

Dissertations, Master's Theses and Master's Reports

Past research has identified East-West differences in visual attention associated with holistic versus analytic perception and reasoning strategies (Nisbett et al., 2001; Boduroglu et al., 2009). These cross-cultural differences might stem from several different mechanisms, which may include: interference suppression, response inhibition, attention to detail vs. object configuration, stimulus centrality vs. eccentricity, number of visual distractors (e.g., display set size or clutter), and others.

Although research has shown East-West differences, the results sometimes appear inconsistent with each other, or they lack clear predictions from underlying theories. For example, evidence of a preference for cluttered displays (Wang et al., 2012), evidence …

Multisensory Cue Congruency In Lane Change Test, Yuanjing Sun

Dissertations, Master's Theses and Master's Reports

Nowadays, a driver interacts with multiple systems while driving. Multimodal in-vehicle technologies (e.g., Personal Navigation Devices) intend to facilitate multitasking while driving. Multimodality enables to reduce cognitive effort in information processing, but not always. The present study aims to investigate how/when auditory cues could improve driver responses to a visual target. We manipulated three dimensions (spatial, semantic, and temporal) of verbal and nonverbal cues to interact with visual spatial instructions. Multimodal displays were compared with unimodal (visual-only) displays to see whether they would facilitate or degrade a vehicle control task. Twenty-six drivers participated in the Auditory-Spatial Stroop experiment using a …
